Hello,
I´m glad that you could reproduce that bug.
I wonder if you have kind of test environment where you check the controls before deploying?
Please don´t take this offensive, but if you would have a simple test app and check a few steps
(switch view format, add/remove appointments, next/prev. day/week/month) with more than 30
appointments in differnent colors, on all platforms, this sort of bugs wouldn´t make it to your costumers...
just my 2ct
